Bind JList When a JCombobox Option Is Changed

[zepernick]

Hello,

I am new to Swing and to WindowBuilder Pro. I am a java dev, but really only develop web apps. I apologize in advance for the noobish questions.

We have a list of Hibernate objects that we have used to populate our JComboBox. Each object in the combobox contains a list that we would like to use to populate the JList when the combo box changes. We were trying various things in the bindings to make this happen, but have not been successful so far.

Are we able to accomplish this using the bindings, or do we need to setup an ActionListener and do something from there?

Thanks,

Paul

I have no idea. Are you able to write the necessary Swing Data Binding code by hand to do what you want?

Eric,

We ended up coding it by hand and it seems to be working.

Code: Select all

comboBox.addActionListener(new ActionListener() {
         public void actionPerformed(ActionEvent actionevent) {
            if (actionevent.getActionCommand().equals("comboBoxChanged")) {
               final Selection selection = (Selection)comboBox.getSelectedItem();
               if (selection != null && selection.getClaimselecteds() != null) {
                  listModel.removeAllElements();
                  for (Claimselected cs : selection.getClaimselecteds()) {
                     listModel.addElement(cs);
                  }
               }
            }
         }
      });



Thanks,

Paul

Good. I'm glad that worked. I was not able to find a way to do this using just the Swing Data Binding API, so using a listener was probably the best way to go.
